The reference ninneral 1, designates an externally threaded metal container or cup, having integrally formed on the bottom thereof a hollownut portion 2, of redliced diameter, on the lower end of which is in-l tegrally formed an externally. threaded mounting tip or shank 3 of a diameter less 1 Q 0 videdfwith a "central passage 4. to coininuni oate"withachan ber 5, saidnut. #The 115 chamber"? designated by the niinierali (i, together with the "chainber 5, and passage 4; thus afford a contini ons funnel shaped pas sage through seid integrally connected mem: be rsforininglthe'base of the, .devic e.

I The brace .plate 9, is brazed or soldered to the ,pin 7, at the meeting ,pointof the round .pin 7, with thesquared stem 8, to permit the lugs 10, to be rigidly secured bybrazing' or other suitable means to opposite sides of the innersurface of the nut 2,. and atthe upper end thereofto afford oppositely disposed I'eStIlCted;OpB11-,

The springs 20, are of sufiicient strength to Withstand the jarring and vibrating actions of the parts upon tion with sufficient force to overcome the re which the grease cup is mounted, and by clamping against opposite sides of the stem 8, hold the cap 13, stationary in a predetermined or, adjusted position, from which position it can be rotatably moved either downwardly orupwardly by manually turning the knurled cap 13, in the desired direcsistance of the locking springs.

The operation of the modified form of the device shown in Figs. 8 and 9, is the same as that above described, except that the springs 20, engage the stem 24, to prevent the grease cupcap 13, from working its way off of the cup 1, due to the j arring or vibratory actions of the parts. When it is desired to feed grease to the parts upon which the grease cup is mounted, the cap 13,

is manually turned to overcome the resistance of the springs 20, thus forcing grease from thechamber 6, through the restricted outlet openings 27, and out through the shankpassage 3. p

I am aware that various details of construction may be varied through a. wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

, I claim as my invention:

1. A grease cup comprising interfitting grease containers, a square stem secured to one container, apertured means secured to Copies of this patent may be obtained for the other container, and a plurality of leaf springs supported by said means and projecting therethrough "to contact opposite sides of the square stem.

2. A grease cup comprising a base member, a cap member, a stem secured to the base member having flat faces, a cylinder having slots therein secured to the cap, and oppositely disposed leaf springs projecting through said slots and secured to the cylinder bearing against opposite square faces of the stem.

3. In a grease cup a base cup member, a

cap cup member, a squared stem, a member a in the passage through which the grease is adapted to be forced, a stem secured to the guide member, a cup adapted to be threaded onto the base, a cylindrical member secured thereto to receive the stem therethrough, and resilient bands, secured to the cylindrical member and frictionally contacting the stem.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
